To all whom it may concern:

Be it known that I, JOHN F. SGHUFFE- NECKER, of St. Louis, in the countyot' St. Louis and State of Missouri, have invented lan improved andusef'ul machine for making bricks of tempered clay; and I do herebydeclare that the following is a full and exact description thereof,reference being had to the ac companying drawings and the letters of'reference marked thereon, in which- Figure l is a side View ot' themachine. Fig. 2 is a front end view.

ln Fig. 1, ais a cross-head, to which a lever is secured to operate themachine. d is a vertical shaft. c and c are spur wheels. ffff are knivesby which the clay is tempered. g is a vertical sha-ft. To prevent theclay from settling into the pan I use the following made, hollow shaftsor solid. his a tube. is a steel pan. v j is a toe, adjusted into'thecross-bar l. It is a cup, adjusted to the toe, and strikes against thelower end of the vertical shaft. The oil is introduced to the pan by thetube h. (See Plate l. Fig. 3.) 'n is a shaft which extends partially atthe rear end of the machine. m is a crank. o is a pinion. Both aresecured to the said shaft. p is a rack. q are the shutters, which aresecured to the said rack by screws. b is the lower part of the hopper.l) is a support secured to the front end of the machine. r is a wheelfastened to the vertical shaft g. s is a horizontal shaft,which extendsacross the front end of the machine. u is a wrist fitted into the crankN. fu is a drivingbar, which extends across the rear end of the machine.fw is a rod which connects the driving-bar to the crank. w is a doublecrank. The upper part of it has a slot. .t is a rod which has a slot atthe left end, and is attached to the driving-bar. The other end isconnected to the lower part of the double crank by a pin. y is a rodattached to the upper part of the double crank. The other end isconnected to the scraper A. c is a spring secured to the said rod. A isa scraper' (in the inside of the machine.) a is the axle of the quadrantB. c are safety openings. l) is a grate. E are the molds. F are rollersupon whichthe molds are moved. Gr is the frame of the machine. zis a'stud. d is a weight attached to the lever j'. The other end of it islinked to the stand h. g is a guide. rIhe upper part of it is secured tothe hopper. At the lower end of it is a setlscrew, h, with a nut and aslot, through which the lever f passes. In Fig. 2, c is a crosshead. inis a crank. g is a guide. h is a stand. j is a part of the fork-lever. Pis a support. t is a cam-yoke. t is a wheel fastened to the horizontalshaft s. z is a stud 5 A, a scraper; E, molds; G, the frame ofthemachine. Narecranks; w,doublecranks. w are rods; c, parts of the driving-bar.- l

The following description will show how the machine is operated: I placethe clay into the hopper, and when perfectly mixed I open the shuttersby the crank fm at the let't side ot' the machine sufficiently to passthe clay. c is a drivingbar, and to which a reciprocating motion iscommunicated by the rod w. A corresponding rod on the opposite side ofthe machine, a set of molds, being placed on the apron in front of thedriving-har. is by a revolution of the. horizontal shafts driven forwardvsufficiently to permit another set of molds to be introduced'into thespace as the drivingbar again retreats. The rod c', attached at one endof the drivin g-bar, at the other end to the lower end ot' the doublecrank by a wrist or pin, moves the quadrant B. The quadrant is moving onits axle a, rises at the proper time to allow the clay to pass to thegrate. Vhen it moves from left to right it presses the clay through thegrate into the molds. rlhe apertures c allow'the superiiuous clay topass out and to be deposited in the empty molds in rear ot' those whichare thus filled. The molds are moved forward previous of the rising ofthe quadrant.

Descriptions and opera-tions ot' Plate 2, Figs. 1 and 2: To prevent theclay from being drawn away in front of the brick, I use a scraper, A,which is raised above the surface ofthe mold as much as necessary, andis brought down as soon as the 'mold has passed the scraper aboutthree-eighths ot' an inch. These two motions are caused by theconnections of the cams t t', fork-leverj, scraper A, and joint K. Thisjoint has a screw on the upper part with two nuts, whichgare for thepurpose of regulatin g the level of the forklever as necessary.

This said joint is fastened to the support P.

(See Fig. l.) After this another scraper, A, moving from left to right,levels down the portion which has escaped the action of the scraper A.This scraper when it moves to` the right is turned in such a position asto rise above the mold, and is held in the same by a spring, z, as soonas the arln I has dropped into the groove of the spring. The changes ofpositions are caused by studs, or as the spring strikes against themachine.

Descriptions and operations of Plate 1. Figs. 1,2,4z To equalize thefriction of the machine I use the following mode: The cam u will raisethe lever as the drivin g-bar is to move from left to right. The saidlever will rest upon thevset-screw as soonv as the driving-bar is tostrike against the right end of the slot of the rod w. (See Fig. 4.)These frictions are caused as the crank N is to pass its centers. Toprevent the clay from settling between the quadrant and the hopper, Itit a set of steel bars into the grooves of the quadrant. These bars aremanaged by set-screws or by springs.' To prevent the clay from settlingbetween the upper part of the quadrant and the hopper I use a plate, S,which is held to the hopper by screws loose enough, so it will move byits own weight or its equivalent. These apertures are for the purpose oftaking oft' the loose motions of the quadrant.

What I claim as new improvements, and desire to secure by LettersPatent, are the following points:

1. The manner adopted by using the toe j, pan t', cup k, and tube h, incombina-tion for the purpose herein described.

y 2. The scraper A, operated by the cams i t, fork-lever j, and jointK', as for the purpose above described.

3. The manner to lsecure the position of the scraperA by means of thespring z and arm I, as shown in the specifications. 4. The manneradopted to regulate the friction of the machine by the cams u u, leverj', guide g, set-screw h, in combination of the slot of the rod at', asshow-n and described in the foregoing specification.

5. The mode adapted to prevent the clay from settling between hopper andthe quad rant by means of the plate S, grooves R, steel bar m, andset-screws Q Q Q Q, or their equivaient, for the purpose set forth.
